4(a)

For a long time it was my dream to start the day by playing sequences of electronic pulses which would move around my study at different speeds, with the distance between the pulses’ entries being able to be varied, from long intervals to coagulations so dense they would – just for a moment – give rise to a held note. I have never made this dream reality at home, but I have in many different ways in pretty well all my compositions. The notion of these ›impulses‹, with the fascinating properties I’ve described, came, of course, from Stockhausen. Around the time of the conception of La disciplina dei sentimenti and Genieting 1 I was engaged in a prolonged study of his Texte zur elektronischen und instrumentalen Musik (Cologne, 1963.) An account of this period of research can be read in the Dutch Journal of Music Theory under the title ›Een lezing voor New York‹ (Amsterdam, 2001.) The article is based on a lecture that I gave in New York in 1995. The most important aspect to emerge from this article was the idea that impulses determined the structure and the course of my music, and that they did so from within and at any moment: that is to say that they could immediately bring about something in the music; as opposed to prefabricated structures, which were designed prior to the genesis of the music. Whether I have succeeded in applying impulses in this way remains, for as long as I continue applying them, an open question. It is, however, a fact that they still fascinate me, also for other reasons, which I will write about in ›Impulses – 2.‹ In ›Impulses – 3‹ I shall explain how they should be interpreted and performed.
